Woo (1964) established the name Sinanthropus lantianensis with the Lantian 1 mandible as the holotype. Groves (1989 p. 202) notes that Wu (1964) proposed the name conditionally (provisionally) and thus the Wu (1965) publication established the name. In this later publication the name is applied to both the mandible and cranium though they derive form different contexts and are not associated. Groves (1989 p. 202) established the mandible as the lectotype for the name established in Wu (1965).
